To be honest guys I am looking forward to the next coupe (m4?).
Being more fuel efficient and more low end get up than an 8k rpm v8 would make it my perfect dd. Not to mention it would be faster in general as well.
The current v8 just drinks too much and wouldn't make my trafficy commute much fun.

I got a friend with a E46 m3 that is debating about picking up a current gen m3 or waiting and he did mention that the horrible gas mileage is the biggest reason for him to wait. But he also likes the thought of getting the last great NA bmw engine.
